Radio-controlled submarines are sophisticated and intellectual tech types of equipment. They can be used to find elements out of water bodies and to also carry out other aqua research and surveys. It is very common to find them used by oceanographers for research and other aqua studies. They are built with sophisticated and high techs to carry out these purposes. There are RC submarines fpv(first-person view) which allows you to have a clear view and study of water bodies. They serve as alternatives to aqua researchers having to go underwater to do their surveys and research works. With these RC submarines, oceanographers and other persons alike can easily take a look at water bodies and do their studies. These RC submarines are controlled to go underwater to take quality and clear footage of whatever study is needed for whichever purpose(s).

Rc submarines can also be used by the military for specific purposes. Here, they engage the RC submarines with torpedoes. These types of RC submarines have torpedoes which detonate upon contact with a target or by the press of a button. The torpedoes are usually added to the build of the RC submarines for this type of purpose.

Buying Guide Questions

The buying guide section will give you practical and reliable answers to common questions about RC submarines. It might intimidate you on how best to go about the use of these RC submarines. Please pay careful attention in order for you to be able to get useful information. It is important to also know the differences between an RC underwater drone and an RC submarine, they are similar, yet completely different.

How Deep Can a RC Submarine Go?

Questions like this are frequently asked and the answer to it, is that there is no one single and particular answer. The answer is rather relative, depending on the particular RC submarine in question. RC submarines generally can not go as deep as normal human-controlled submarines, but this does not mean that they cannot penetrate water too. On average, RC submarines go as deep as 3.5 meters. Not all submarines can go as deep as 3.5m, this is just on average. Some submarines can go deeper too. It all depends on the radio transmitter, motor strength, and propeller of such RC submarine. Some RC submarines like Jujuism and ThorRobotics RC submarines have a combined strong radio signal with a strong motor strength, making them capable of going as deep as 4metres.

How do RC submarines work?

RC submarine work through a radio signal. They receive signals from the radio transmitter which is held by the person controlling the submarine. And this radio transmitter has different instructions and commands which when imputed steers the RC submarine into action. RC submarines receive the movement, direction, levitating, and the emerging signal from radio transmitters. What is more? RC submarines have propellers in order to be able to obey movement signals from the radio transmitters. Propellers enable RC submarines to make any movement underwater and afloat it. The stronger the propeller, the faster the movement. Some RC submarines even have double propellers for enhanced movement. There is also a liquid gas that enhances proper movement. And this is the aspect of gas-powered RC submarines. RC submarines have liquid gases situated in the ballast tank. The ballast tank with the help of the liquid-gas blasts out water that enters the tank underwater. It helps the submarine move and also prevent it from sinking like an RC Sailboat would if not handled correctly!

Added to all these are LED lights and streamlined bodies. It’s the steam lined bodies of these RC submarines that enable them to be able to move seamlessly underwater. The LED lights also enable clear and bright vision. RC submarines are then equipped with video and picture capacity- this feature is the most important feature of an RC submarine to an aqua researcher. The feature enables footage of aqua study to be taken for study purposes.

All these features put together make RC submarines effective for their made purposes. They enable seamless movement together with clear and sharp footage of aqua study.

Can Wifi or Bluetooth work underwater?

Wifi and Bluetooth might work underwater depending on the water waves but the truth is that they would not work. This is because both wifi and Bluetooth devices use 2.4GHz radio frequency which does not work well underwater- it’s due to the law of physics as the water molecules would attenuate the signal waves. More so, the Bluetooth signal is low power, the range underwater is just a few inches. The same goes for the Wifi signal. They share the same 2.4GHz radio frequency with Bluetooth signals, so the signal would easily be absorbed by water. However, there is a chance that your wifi or Bluetooth signals would work underwater depending on the water waves. If the waves are not so stormy. But generally, wifi and Bluetooth do not work well underwater, their 2.4GHz radiofrequency is just too low for that, if you are looking for an RC Drone with longer range, then there are options available.

What is the fastest RC submarine in the world?

There is no particular RC submarine in the world that can be pointed to as the fastest, as the performance of RC submarines depends on the water conditions too no matter how sophisticated. But there are some RC submarines that are top-rated for their speed. When it comes to speed, the Jujuism mini RC submarine and Submariner by sea-peep are top-notch in the world. Jujuism in particular has a 6-channel design and powerful propellers suited for high speed. More so, it has a waterproof design to ensure the propelled builds are not destroyed by water. The submarine by sea-peep is also top-notch for speed purposes. If you are looking for an RC submarine for speed purposes, choose these ones.

Insider Tip: race using RC Drift Car vs. a RC Submarine to settle any bet, not sure which one will win every time, but there is only one way to find out for sure!

It is also important for you to note that the water conditions can also influence the speed of an RC submarine. If the waves are soft and mild, an RC submarine would move faster even when it is not a Jujuism or submariner. A submariner or a jujuism would not go as fast when it is placed in windy and stormy waters. That is how it works.

Does RC work underwater?

Radio transmitters work very poorly underwater-this is because they use the 2.4GHz radio frequency The water waves swallow up their signals, leading to ineffectiveness. The fact is that if you wish to use the 2.4GHz radio transmitter frequency to dive underwater, you have to completely insulate it from water. The receiving aerial needs to be completely insulated from water. And this would allow the RC to work well. RC can indeed work well underwater, but they need to be completely insulated from water and liquids.

How deep can radio waves penetrate water?

Modern radio waves use the 3-30kHz radiofrequency. This frequency can penetrate approximately 20 meters underwater. Also, this frequency also needs favorable water conditions to penetrate well. If the water conditions are calm and mild, they would penetrate well, this works well for RC Hovercrafts as well, you can’t technically go underwater with them, however, they still move fast and can accompany or work well alongside your RC submarine.

What frequency do RC submarines use?

RC submarines use the 75mHz frequency. It’s the only frequency that would work underwater for the transmission of any signal. Also this frequency allows the boat to move, levitate, emerge, and do other things underwater. More to that, the frequency is recommended mostly in the United States of America but also in other major parts of the world.

Can you use RC submarines in saltwater?

Yes, you can use RC submarines in saltwater, but not all of them. There are some RC submarines that are not suited for the acidic nature of saltwater because they would damage the electrons and some parts of the RC submarine. On the flip side, there are RC submarines that are very good to use in saltwater. Examples of such RC submarines are the Submariner by sea-peep, ThorRobotics RC submarine, and The Jujuism mini RC submarine. These RC submarines can be attached to sea vessels alike. They are perfect for saltwater, the acidic nature does not affect the RC submarine parts.
